Josh Eoraki: Stardome astronomer ahead of the first all-civilian private spacewalk

The stage is set for the first ever all-civilian commercial spacewalk. Tech entrepreneur Jared Isaacman, alongside a a pair of SpaceX engineers and a former Air Force pilot blasted off earlier this week - and if all goes well, the walk will take place in a few hours. Stardome astronomer Josh Eoraki explains that space is an inhospitable environment for humans - meaning the crew is carrying out a risky mission.  "There's no air, you'll suffocate - it's extremely hot if you're in the sun and it's freezing if you're in the shadows. It's just the most inhospitable environment for humans." LISTEN ABOVESee omnystudio.com/listener for privacy information.
